An interesting article by Paul MacInnes in The Guardian about when and how spectators might be allowed back into sports events. Among the ideas to make this safe are:

• Grounds only one third full
• No away fans
• Toilets locked at half time
• Staff bringing alcohol to spectators in their seats
• Designated arrival times
• Incentivising parents and children to attend
